vitality his habits, too, may change. He may likewise learn by
experience, and through the comparing and recalling of experiences and
their consequences may build up rules of conduct which will restrain him
from doing certain things that he otherwise would do. Anything that
increases his knowledge and adds to his experience will naturally affect
his habits and will either build up or tear down inhibitions or do both,
as the case may be. If he has intelligence he knows he is always the
same man; that he has not reformed nor repented. He may regret that he
did certain things but he knows why and how he did them and why he will
not repeat them if he can avoid it. The intrinsic character of the man
cannot change, for the machine is the same and will always be the same,
except that it may run faster or slower with the passing years, or it
may be influenced by the habits gained from experience and life.

We must learn to appraise rightly the equipment of every child and, as
far as possible, of every adult to the end that they may find an
environment where they can live. It must never be forgotten that man is
nothing but heredity and environment and that the heredity cannot be
changed but the environment may be. In the past and present, the world
has sought to adjust heredity to environment. The problem of the future
in dealing with crime will be to adjust environment to heredity. To a
large extent this can be done in a wholesale way. Any improved social
arrangement that will make it easier for the common man to live will
necessarily save a large number from crime. Perhaps if the social
improvement should be great enough it would prevent the vast majority
of criminal acts. Life should be made easier for the great mass from
which the criminal is ever coming. As far as experience and logic can
prove anything, it is certain that every improvement in environment will
lessen crime.

Codes of law should be shortened and rendered simpler. It should not be
expected that criminal codes will cover all human and social life. The
old method of appealing to brute force and fear should gradually give
place to teaching and persuading and fitting men for life. All prisons
should be in the hands of experts, physicians, criminologists,
biologists, and, above all, the humane. Every prisoner should be made to
feel that the state is interested in his good as well as the good of the
society from which he came. Sentences should be indeterminate, b
